Nanosecond transient absorption spectra of Ir-2. a Ir-2, b Ir-2 with 40 mM of DMT, c reduced Ir-2 with 0.2 mM of C-1; d the decay of Ir-2 at 468 nm, e kinetic traces of reduced Ir-2 followed at 500 nm, f kinetic traces of reduced Ir-2 with different concentration of C-1 followed at 500 nm. These spectra were recorded in CH₃CN after pulsed excitation at 355 nm under N₂
